Having protagonists of all games in one place is a weird thing. Because CJ, Tommy and Claude are really old now. Tommy, for example, is 50 and I don't think Claude is younger! CJ should be around 40-45. Victor's dead. Toni's also old. In Toni's case, he isn't even able to run (It will be something like playing old Altair in Assassin's Creed Revelations). Also, you haven't mentioned Huang Lee, Johnny Klebitz and Luis Lopez.

Assuming there all the same age

I think Trevor would do well because he's just crazy and Rockstar wanted to show how badass he was for taking down Johnny and the Lost, the gang you played as in IV!!
